Once there was a boy and a girl. They met at a comic book store. They quickly fell in love and often shared their favorite comics. But one day, the boy had to move far away for his family. The girl was heartbroken. She would look at the comics they once shared and cry. Their love, which started so happily among the comics, ended sadly with distance.
Once there was a little dog in a comic. It was always left alone at home while its owner went to work. Day by day, it waited by the door, looking sad. One day, it thought its owner was back but it was just a passer - by. The disappointment in its eyes was heart - breaking.
Well, one common theme is heartbreak. For example, a character in a comic might experience the end of a relationship, and the panels would show their sadness through their expressions and body language. Another theme is isolation. Maybe a character is ostracized by society for being different, and the sad comic would depict their struggle to fit in or their acceptance of being alone. Also, failure can be a theme. A character fails at achieving a goal they've been striving for, and this causes great sadness in the story.
There was a sad comic story about a little dog. The dog was always waiting at the bus stop every day. It turned out that its owner used to take that bus to come home every day. But the owner passed away in an accident. The dog didn't know and still waited, which was really heart - breaking.
To my knowledge, there aren't any sad story porn comics with Yamcha. Such content would be quite unusual and may even be against the law in many places.
Well, a common element is the presence of something that once brought them together but then causes the separation. In a comic sad love story, it could be a special comic. Maybe they fought over who should own it in the end, breaking their relationship. Another element is the feeling of loss. Losing the love that was once as colorful as the comics they loved. And jealousy can also be an element. If one of them is too jealous of the other's comic - related friendships, it can lead to a sad ending.
